I went to the range yesterday. As always, somethings worked out well and others didn't.
I started with the normal load, using triple 7, at 50 yards. 2\3 shots were right on, with the third being a flier. This flier business, I've always blamed on my shooting skills. However, when I switched to real black powder the fliers stopped. I was on at 50 yards, a little high at 25 yards.
I had painted the front bead sight white and that worked great out to 50 yards.
At 100 yards, later in the afternoon, the white bead seemed to disappear. I concentrated so hard on trying to see the white bead that my eyes began to hurt and water so bad I had to quit shooting. The balls weren't hitting the target and it was hard to find out where they went. I finally found my hits had grouped fairly good on the back board below the target.
It caused enough problems for my eyes that I spent a long time cleaning my gun at the range rather than attempt to drive home. I don't know why my old eyes had so much trouble with the white bead. On the other hand, I could see the post under the bead fairly well and of course when I used that my shots went really high.
